UPDATE: Thomas has announced her retirement.
Her comments [telling Israelis to leave Palestine and "go home" to Europe] do not reflect a desire to see Israel/Palestine judenrein, but rather an ominous sense of what a dangerous place Israel has become, and will only increasingly be, for its people.
But the more important point is that the cries of "historical ignorance" by the Zionists only reflect their own. It was the Zionists, with a mighty assist from Stalin, who stood in the way of the surviving Jews of Europe being able to return to the only homes they ever knew. The anti-Zionists of that time, most notably the great Lessing Rosenwald, passionately and rightly argued that the suggestion that the Jews should not simply cast down their buckets but be transferred en masse to Palestine was an insult to all that the war against Hitler had been fought to achieve. Along with his friends in the Reform rabbinate, Rosenwald had also not been shy about calling out the proposition that there existed a Jewish "nation" for what it was - a fundamental and dangerous concession to the doctrine of Hitler. Indeed, per Helen Thomas, there could be no happier consequence of the fall of Zionism than the rebirth of Judaism in Poland that we have already seen in Germany.
